Nowadays, there are all kinds of lotteries in our society. Wherever you go, you will see the advertisements of lotteries on TV, on newspapers, in the streets and so on. These lotteries are divided into welfare lottery, sports lottery, computer lottery, and so forth. Meanwhile, there are quite a few people buying them.

But why are there so many people buying lotteries? Why are the lotteries so popular? In my opinion , there are three reasons for this. First, most people are trying their luck on lottery tickets. They have a long-cherished dream of making big money overnight. Second, some people just like it and it can make their life more colorful.

Finally, there are some people who want to make donation to public welfare by buying lotteries.
